I I m attomwt ol Patented Jan. 10, 1933 PATENT OFFICE LOUIS K. SALSBUBG, OF WILKES-BARBIE, PENNSYLVANIA FROZEN GONFECTION PACKAGE Application filed April 22, 1832. Serial No. 606,981.

The invention relates to improvements in packaging means for frozen confections, of the nature in which the so-called dry ice (carbon dioxide snow) is used to prevent melting of the confection for a predetermined period of time. Heretofore, when packaging ice cream and the like in the customary ways, the extremely low temperature of the refrigerant has been transmitted to the cream or the like, freezing the latter so solidly that it could only be removed from the container with difiiculty, unless allowed to stand until it partially thaws. -My invention however, aims to overcome this difliculty in a novel and advantageous manner, being such that it positively prevents freezing of the cream or the like to a'consistency materially harder than that which it possessed at the time of packing.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a top plan view of the package preparatory to insertion of the refrigerant and closing of the carton.

Fig. 2 is a vertical sectional view through the closed package. m Fig. 3 is a perspective view showing the apertured insulating partition which supports the refrigerant, and the upper end of the confection container upon which said partition rests.

Fig. 4 is a horizontal sectional view illustrating a circular carton and partition instead of the rectangular formation illustrated in the other views.

In Figs. 1 and 2, a fibre board carton 10 of rectangular form, is shown, said carton being of conventional construction, having a flap-formed bottom 11, a side wall 12 and topforming flaps 13, the latter being foldable in the usual way and adapted for securing by adhesive strips or the like to close the upper end of the carton. Due to the nature of the refrigerant used within this carton, it is essential that gas be permitted to escape 50 from the latter, and this is allowed in the Various crevices between the top and bottomforming flaps.

Into the carton 10,1 place the conventional container 14 for the ice cream or the like 15, said container being usually formed from waxed cardboard. The container and carton are of such heights that the upper end of said container is downwardly spaced from the upper end of the carton. As usual, the container 14 is closed at its upper end by a flanged cap 16 which includes a continuous upstanding rib 17, constituting the seam which joins the flange and the cap proper toget er.

I provide an insulating partition 18 of fibre board or the like, of a size to rest upon the rib 17, said partition serving to support the refrigerant 19. This partition 18 is formed with openings 20 from its upper to its lower side, said openings being preferably 70. in the form of notches in the corners of the partition. Each 0 ening extends both inwardly from the ri 17 and outwardly from said rib, thereby placing the space 21 (between partition 18 and cap 16) in communica- 75 tion with the space between the carton 10 and the container 14. The refrigerant 19 is preferably of such size that it does not extend over any ortions of the openings 20 but this is not a solutely essential. w

The partition 18 prevents the refrigerant 19 from directly contacting with the container 1d and hence severe chilling of the cream or the like by contact is prevented. Moreover, the openings 20 choke down the descent of the cold gas given ofi by the carbon dioxide snow when melting. Some of this gas of course descends to fill the lower portion of the carton 10, and some of it passes through the openings 20 into the space 21. 90

The gas may efi'ectively circulate to maintain substantially a uniform temperature in the carton to prevent melting of the container contents, and at the same time lowering of the temperature sufficiently to freeze said contents to an undesirable hard state, is prevented. v

In Fig. 4, a cylindrical carton 10 is shown receiving the container and the partition 18 which corresponds with the partition 18,

isof'circular instead of square form, The

openiifis 20 of partition 18" may well be V aped instead of rectangular as the opening? 20. I

5 Exce ent results have been obtained from the exact details disclosed and they are therefore preferably followed. However, within the scope of the invention as claimed, minor variations may be made.

l I claim A frozen-confection package comprising a carton closed at its top, bottom and sides, a confection container within said carton and spaced downwardly from the top thereof the 15 top of said container having an upstanding peripheral rib, an insulating partition restmg removably upon said rib and by the latter supported above the major part of said contamer top to provide a pocket, said partition having gas conducting openings from its upper to its lower side, part of each opening extending inwardly from said rib and the remainder outwardly from said rib to place said pocket in circulatory communication with 25 said carton, and a gas-formin refrigerant resting on said partition, said re rigerant and partition being freely removable when the cartonis openedQ 1 In testimony whereof I aflix my si ature.
